SPECIFICATION forming part of Letters Patent No. 521,748, dated June 19,1894.

Application filed January 11,1893. Serial No. 458,000- (No model.)

My invention is an improvement in oil or.

lamp stoves and relates particularly to the manner of attaching the conestand and base together; also to the manner of holding the chimney inplace and connecting it with the other parts, further to a special formof detachable hinge connection between the cone plate and stand or base.

In the drawings Figure 1, is a side view of the stove, partly in sectionand Fig. 2, is a sectional plan view. Fig. 3, shows details of thehinge. Fig. 4, is a plan, and Fig. 5, is a rear View of a modified formof hinge, and Fig. 6 is a plan view of the hinge of Fig. 4

turned back. Fig. 7, is a detail view of the handle. Fig. 8 is a detailview of the bearing for the handle.

The cone stand 1, is att-ached to the base by springing one part intoconnection with the other and in this my invention consists broadly.In'the present instance the cone stand is provided with lateral anddownward extensions 2, in the form of feet, which rest upon the upperedge of the base'3, and have hooked projections which extend over andbelow ahead or flange 4, on the said base. By this construction thestove is supported and the basewhich may be made of sheet metal .with aflaring upper rim is prevented from spreading when the stove issubjected to the weight of the articles being heated. Theflaringoonstruction of the base provides a pan likereceptacle, in whichthe-wick tubes are located. By springing the parts into connection witheachother no special form of connection or holding bolt is necessary andI do not wish to limit myself as to which part is sprung into connectionwith the other. In theform shown the hooked feet merely extend over theflange or bead and no bearing or connection is necessary with the innerpart of the rim. I do not wish to limit myself, either, to the form ofbase shown as this may be varied as desired though the form shown is ofmaterial advantage. The cone plate 7, is formed with an annular rimagainst which the drum is adapted to hear at its lower edge, this rimbeing marked 5, and the drum 6. The drum is formed of sheet metal ofsufficient length to pass only partially about the flange so as to leavethe front opening for the door, and in order to secure the drum in placelaterally I have provided interior projections 17 on the door plateadapted to pass through openings formed near the ends of the drum shell,these projections preferably extend at an angle to the door plate, andform a hooked connection between the same and the shell of the drum sothat the door plate serves to connect the two ends of the shell as wellas serving to support the hinged part of the door, these projections arepreferably cast with the door plate. The term cone stand as used hereinis applicable toany desired form of support for the cone or upper partof the stove.

The special form of hinge connection is provided for the purpose ofallowing the chimney to swing entirely back, so that its edge will reston the surface of the table or other support upon which the lamp isplaced, to be supported thereby, and adapted further to maintain thechimney inpivotal connection with the base or cone stand, until thechimney is swung below the plane of the base, whenit can be entirelydetached if desired. At the rear upper edge of the cone stand lugs 15,project rearwardly having lateral projections 16, reaching inwardlytoward each other. These extensions are rounded and form pintles for thehinge hooks 17 extend ing down from the cone plate, passing on the frontside of the pintles and between them and the cone stand around beneaththe said pintles and about all the way up the other lateral studs 14,"are formed, extending longitudinally of the pintles to bear thereon onthe side opposite to that embraced or borne upon from the base or conestand as the case may be, and it will be seen that this feature isespecially desirable and it may be said necessary where the lamp islight and is incapable of sustaining the chimney when tilted partiallyto the rear. The hook is, as before stated, substantially semi-circularand it together with the lug thereon, almost entirely encircles. thepintle. Said pintle is cutaway on its rear side at the point 148 wherethe lug would hear on the rounded surface, were the chimney swung stillfarther down and below the table surface or the lower plane of the base;\Vhen so swinging the lug 14, comes over this cut away part and dropstherein, the hook is then free to be removed from the pintle, thechimney then being in inclined position relatively to the base. It maybe swung back in this position either by raising the base slightly fromthe table, or by moving the lamp to the edge of the table. The cut awaypart, it will be noticed is specially arranged in relation to the lugand hook that is to say, it is in rear of the axial line of the pintle,and the surface extends in inclined position downwardly and forwardly,so that the chimney must be turned to the extreme inclined positionmentioned, below the plane of the base, before the lug can drop into thesaid cut away part. In Figs. et and 5, is shown a modified form of hingein which the hooks 7 X are a part of the frame or base, the handle framein the present instance; and the pintles areon the cone plate andcomprise a cross bar 8 to lie on the rear side of the said hooks, thisbar being confined against displacement by a lug 9 on the handle hearing on the rear of the cross bar. As in the previously described form ofthe hinge the pintle is cut away at one part so that the hooks andpintles can be disengaged when the chimney is thrown back at a certainangle to the base. In the present instance this cutaway part is shown at10 on the under side of the pintle bar. The hooks bear laterally againstthe shoulders or lugs 11 until the chimney has been swung back at theproper angle so that the end of the hook comes opposite the cut awaypart and then bya lateral movement of the chimney the pintle bar ismoved lengthwise through the hooks and the parts disengaged. It will beunderstood that this form of hinge may be used on the cone stand ifdesired or the form previously described may be on the handle and thishandle may be sprung in place; to this extent the parts areinterchangeable. The handle 10, has its upper end bent down, and thisend 11, is enlarged and bifurcated or grooved transversely of its end.The said groove has I a curved bottom and this end is adapted to thelugs 12, projecting up from the rear edge of the base. The bearingsurface between these lugs is curved as well as the seat 13, at theendof the handle and when the handle is in place, the curve of thebearing and the groove will hold the handle securely against the lateraldisplacement. The handle issecured by being sprung into place, the lowerend being bent to pass beneath the bottom of the base and having a pinto fit a hole or socket in said base. As shown in dotted lines at 20,the said handle may be sprung into place so that its upper end willengage the upper part of the stove while its lower end will engage thelower part and thus it will serve as a connection between them.

\Vhat I claim is- I 1. In an oil stove the base and the cone stand, saidparts being sprung into connection with each other, substantially asdescribed.

2. In combination, the base having a bead or flange and the cone standhaving the hook projections or feet to connect with said flange, theconnection being formed by springing one part into the other,substantially as described.
